PROCESS AND DEVICE FOR FINISHING TEXTILE FABRICS AND THE LIKE.

Application filed February 27, 1922. Serial No. 539,529.

To all whom it may concern Be it known that I, PAUL EDLICH, a citizen of the United States, and resident of Delawanna, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Processes and Devices for Finishing Textile Fabrics and the like, of which the following is a specification.

This invention relates to the process and machine for finishing textile cloths or fabrics in general, and particularly to the kind where a certain surface effect is imparted on textile merchandise and similar material, requiring a high grade of finish.

One of the primeobjects of my invention is to provide a novel process whereby a natural appearing, uniform finish is imparted to a material, first at the so-called reverse side thereof, whereafter the riht side is treated to attain a higher finish e ect than at the reverse side.

Another object of my invention is to provide a process for chemically and mechanically treating a material whereby its surface or surfaces are improved by a series of successive mechanical smoothing operations, after the surfaces have been subjected to chemical treatments.

Another object of my invention is to provide mechanical means for facilitating the successful application of such process.

A further object of my invention is to provide with such a machine, means whereby the material to be finished is yieldably supported alternately at one of its surfaces, while its other surface is mechanically treated.

The foregoing and further objects will be more fully apparent from the following description and the accompanying drawin in which:

ig. 1 is a 'diagrammatical plan view of a referred form of my device.

lg. 2 is a side elevation thereof.

Fig. 3 is a diagram showing the mode of the driving parts of the mechanism.

Referring to the figures, numeral 1 designates the stationary frame, which is provided with side brackets 2 in which guide supports 3 and 3 are provided for an adjustable frame 4.

The adjustable frame 4 rests upon manually operable adjusting means indicated at 5 of any convenient construction.

Extending from the'guide support 3 is another stationary frame 6, serving as suspension for the guides 7 and .8 and the wind-up 9 for the finished goods.

Extending from the opposite side of the stationary frame is a bracket 10, supporting a roll of unfinished goods, indicated at 11 and tension means indicated at 12.

On top of the stationary frame is mounted a series of rollers 13, 14, and 15, which are preferably covered with a' resilient material, as for instance, felt, velvet or plush. lndicated at 16. I Also mounted upon this stationary frame 15 an adjustable apron indicated at 17, supported by a series of rollers 18 and driven by the rollers 19, 20 and 21. By means of a take-up indicated at 22, the apron 17 may i be stretched or slackened.

Mounted upon the adjustable frame 4, there is a similar traveling apron 23 provlded, which is disposed opposite the roller .SGI'IBS 13, 14', and 15, and so arranged that 1ts yieldable portion faces the middle roller 14.

Adjacent the apron 23, there is another series of resiliently covered rollers 24, 25, 26, 27, and 28, facing the spaces between the rollers 19, 20 and the rollers 18 of the adjustable apron 17. I

A driving mechanism indicated at 29 is adapted to rotate the end roller 21 of the adjustable apron 17 and also the lower and the upper series of rollers, as shown in Fig. 3.

A take-up indicated at 30 for the driving means 31, transmitting motion to the roller series, permits the various adjustments of the roller series towards their respective aprons.

As will be noted from the diagram in Fig. 3, roller 13 in the first series turns in clockwise direction, roller 14 in anti-clockwise direction, roller 15 in clockwise direction again, roller 24 in anti-clockwise direction and roller 25 in clockwise direction, and so on.

Between the tension means 12 and the first roller 13 of the lower series, there will be noticed a roller 32, dipping into a pan 33, which is filled with a fabric treating agent for cleaning, eliminating streaks, and

imparting uniform appearance to the goods, and further adapted to impart, together with the mechanical operation of the device,

a natural appearing, improved finishingeffect to the lower face of the material.

FiElSGlit:

A similar device comprising a container 34 on top of frame 4, and having drip-cocks indicated at 35 provided, also contains a treating agent for supplying the upper surface of the goods. It will be noted that the application of the agent takes place before the goods have reached their respective aprons. p

Such agents as mentioned before, consisting preferably of the following main ingredients, which may be changed according to the quality and structure of the goods to be treated. They are: waxes, aromatic aetheric oils, fatty acids and vegetable oils compounded in various proportions.

The material to be finished is placed in rolls upon the bearings in bracket 10 and are passed through tension means 12 over roller 32 and over roller 13 passing from there between the lower roller series and the upper apron, and then between the upper roller series and the lower apron.

Leaving the apron, the finished goods pass over the guide roller 7, and over guide roller 8 to the wind-up, indicated at 9.

The cloth is shown in the drawings in dashed and dotted lines, which can be readily followed.

The operation of my device is very simple. The lower surface of the cloth to be finished is supplied with the chemical agent from tank 33 and is drawn by roller 13 forward between the apron 23 and roller 14, which travels in opposite direction, and faster than the cloth. In this manner a certain finish is imparted to the cloth, at the point between the traveling apron 23 and roller 14:.

The apron 23 will give to a certain extent whereby a pressing contact is achieved between the roller and the cloth, which latter bears against apron 23. Now the cloth travels over rollers 15 and 24; into the space between the upper series of rollers and the adjustable traveling apron 17.

The chemical agent contained in tank 34 is evenly distributed upon the right side of the cloth.

The material is now pressed between the upper series of rollers and the spaces between the apron supporting rollers 18, 19 and 20.

Through the different direct-ion of rotation of the upper series of rollers and through the pressure exerted against apron 17 by the upper frame in downward direction, a perfect surface contact between the rollers of the upper series and the upper face of the cloth supported by the traveling apron is accomplished.

Since there is a greater munber of rollers in the upper series, the finish of the upper surface of the goods will be more complete than that of the lower surface.

As may be seen from the drawings, the

lower apron is traveling at a slower speed than the rollers, due to the transmission arrangement. indicated at 36.

The material having passed over the apron and over roller 21 is guided over rollers 7 and 8 toward the Wind-up indicated at 9.

By way of adjusting means 5, the adjustable frame t and therefore the pressure of the rollers against their respective aprons may be regulated.

From the above it will be noted that the finishing of the lower surface of the material is accomplished before the finishing of the upper surface of the material takes place; while the finishing of the upper surface of the material takes place after the finishing of the lower surface of the material is accomplished.

While this method has proven to be of great advantage in imparting a high grade iinishingetfect at the right side of the goods and a correspondinglesser finishing effect at. its reverse side, due to the fact that the reverse side first receives the finishing treatment and that the chemical agent applied to that side has fully saturated it, and that the reverse side now serves so-to-speak as reinforcement for the finishing operation of the upper or right side, be it understood that the operation may be reversed or alternately employed, so that the first finished side serves as reinforcement for the successive operation of the other side to be finished. It is also possible to impregnate both sides simultaneously with the treating agent and then alternately apply the mechanical finishing treatments.

The principal of treating cloth or fabric material, alternately in opposite directions against yieldable supports, represents one of the important features of my device, whereby an exquisite finish attalned.

The mechanical construction of my finishing device may of course be changed and simplified in various ways, and I therefore reserve for myself the right to make improvements or changes intended to facilitate the operation of such a device to the best advantage attainable.

Having thus described my invention, I claim:

1. In a machine for imparting a natural appearing finish to a textile weave or similar material, the combination of a series of rollers adapted to alternately rotate in reverse directions and bear against the reverse surface of the material, a traveling apron disposed opposite said rollers and yieldably supporting the material at its future right surface, another series of rollers, having a greater number of rollers than the first series, adapted to alternately rotate in reverse dlrections and to bear against the right side of the material, a traveling adustable apron disposed opposite said second series of rollers for yieldably supporting the material at its finished reverse side, means for adjusting. the tension of said last apron, and means for supplying a chemical fabric treating agent to the respective surfaces of the malterlal prior to being mechanically treated by said series of rollers.

2. In a cloth finishing machine, the combination of a stationary and an adjustable frame, a series of rollers adapted for mechanical treatment of the future reverse surface of a material lodged in the stationary frame, an adjustable traveling apron operatively mounted on said stationary frame, a traveling apron facing said series of rollers and operatively supported by said adjustable frame, another series of rollers also supported by said adjustable frame facing the adjustable apron, a driving mechanism for said rollers adapted to cause the rollers of the respective series to rotate alternately in clockwise and anti-clockwise directions, a take-up for said driving mechanism, means for supplying a chemical cloth treating agent to the material prior to bein mechanically treated successively by the said series of rollers, and means for facilitating the regulating of said adjustable frame, and thus the pressure of the rollers against their respective traveling aprons.

3. In a cloth finlshing machine, the com-' bination of stationary and adjustable frames, a series of rollers, having resilient suspended by said adustable frame, and so arranged as to allowits'yieldable parts to be compressed by said rollers, another series of rollers, greater in number, having resilient coverings, suspended by said adjustable frame and facing said adjustable apron, said rollers being so arranged as to press against the yieldable portions of said apron, and means for facilitating the adjustment of'the pressure between sald series of rollers and their res ective aprons.
